Answer:
it will take 4 seconds to travel 2 meters.
Answer:
S=400m
Explanation:
Given t=10.and ,
Initial velocity,, of the car is zero.
To find distance,
Therefore, car's position after 10seconds is 400m away from the start.
The momentum is calculated by multiplying the mass and the velocity of the object.
momentum 1 : = (10 g)(4 m/s) = 40 g m/s
momentum 2: = (1000 kg)(0 m/s) = 0 kg m/s
Thus, the paper airplane has a greater momentum than the real airplane.
Answer:
Explanation:
Given
See attachment for graph
Solving (a): The graph equation.
Pick two points on the line of the graph
Calculate the slope (m)
The equation is then calculated using:
Solving (b): Solve for t when
We have:
Substitute:
Collect like terms
Divide both sides by 50
